lh, it known that l, Atrium lnostrir, a citizen of tho` Unitnd Statv, and rnsidvnt ot .Roclwstmg County ot' Monroe, Stato ol` Now York. havo invvntml an linprovvnlmit in h'[0lal-\l'orl in;r Ford hltrhanisms, of whirh tht` followingr drsrrii'ytion. in.

Thisl inrrntion rvlat'w. to trod wilma-tions for nntal workin; mat'hiufay sllt'h a. horingl mill4 and` thr liln.

Referring' to th(` drawingn:

Th(l gral' l5 is turnwl Htlpdrv-step hy a pawl and ratrlwt dtwirn 1H hy nwans ot gear t6 from a .yoli'i` arnl lll mounted vontuntrirall,\' withl said guar and oporativvly vonnm'tml with one 0nd ot' a pitinan 20.

'In arrorilam'r with in v inrrntion the otlu'r or lowqr vnd of thi pitinan i aquiplmd with a pivot hearing block Q1 which is fitted tu slide in a slot way 22 thereof which extends lengthwise of a lever arm 23 pivoted in a hravlot` holtnd to the Crossrail structure at, 24. Thrl outer rxtvnsion of this lever arm has pirottd thvrc'to at 35 a vpitman '26 ha ving,r a rrank pin ronnortion 27 to a worm wheel fear 29 journalwl at 29 toy a stud shatton tht` upright. Tho worm gear Q8 is engaged hy a worm 30 tixml on thel upper end f `a 00utantl v driven halt 31 which is journaled to thv rohunn as sern at 32. This shaft 3]. whirh is a fi-aturn of present standard constructions i:-. connvrtril in suitahle. manner (not Shown) to he driven Constantly from the) prinz(l drii'ishalt of the machinn and in unison with tht tahln or hod movvment. The pivot hlorl( 2t has in thlnaded engagement', thvrcwith a sci-ow shaft the outer end 0|' which i5 Hwiveled in the lever arm 23 as Seen. at 34 and equippod with a handley 35. In use tho worin wheel 28 is Constantly driven from the yEhal't 31 and by the Pitman connection 26 omillatvs tht` lewr arm Q3. This oscilla` tion i5 transinittml through the pitman 20 and tht` yoke arm 1S) to impart a step-by-step forward inovcn'wnt to the feed gears 15, 16 through the ratchft device 18. The rate of t'vml lnowniont thus transmitted will be delvrininril ,hy the adjustmentof the pivot hlovh 2t in thtL Slot 22 of the arm 23 and thi` may hu adjusted with precision b turning otE thr rrank handh` 35. It iS to e pal'- ticnlarly notml that with the present` c011- slrnction tho` handh 555 living carried by the arm 2? is onlyY osuillatml through a relatively small arc in the operation of the machine and boing relatively close to the pivot 24 of sa id arm` its range of oscillation is comparatively lmall and thus it results that the svruw xahaft: 33 may be readil turned to adjust the rate of feed duringr tlic operation of tho` mat-hin@ and without in anv Wise intvrt'm'ing therewith. projfrting from the forward und of the arm 23 as shown, is in a particularly convenient and :u'wssihln position from the normal stiation ol the operator. I am aware that the inrintion may he Omhodiod in other specific forms without departing!I from the spirit or nsscntial attributes thornof, and I therefore` desire the prcwnt muhodiment to be con- .sidored iu all rvspm'ts as illustrative and not rvstrirtiro. rotvroncv hiring had to the appended r'lziim rfi/livr than to thi` torngoing Further the lhandle 35 description to indicate the scope of the invention.

Havingl deserihed my invention, what l claim as new and desire to secure hy Letters 5 Patent is:

10 'movement thereto, a gear engaging said paw! and ratchet device having a pitrnan connected therewith to oseillate the saule, a pivoted level' havingr a hingxtudinal Aalot;

therein in which an end 0f said pitman is mounted for adjustment toward and from the lever pivot, an adjusting screw mounted in said lever for adjusting Huid pitman end and arranged at the side of the machine for convenient actuation, and constantly driven gear connections haring a second pitnian connected thermvith and also engaged with said lever for imparting a Swinging movement thereto.

In testimony 'whereof l have signed n1 naine to thih specification.
